How does it work?

Sand enters the machine and is propelled up a blast tube
with air provided by a turbo blower. As the sand accelerates
up the tube to impact a conical target intensive sand scrubbing
is achieved to remove layers of binder material. Removed
binder and unwanted fines are exhausted to the dust collection
system. Sand can be recirculated within the same cell or
passed to successive cells. After the desired amount of
cleaning has been achieved the sand is discharged over
a final screening operation before being returned to the
sand system.
